So as always to fill up their sins. Everywhere the word of God speaks thus of God's judgments: terrible punishments overtake men when the measure of sins is filled up, as for example in Gen 15:17. God instructs sinners in every way. But when they stubbornly reject God's saving arrangements concerning them, then God gives them over into the hands of their own will.
Then, adding sins to sins, they fill up the measure of sins and exhaust God's longsuffering. Inexorable judgment follows. The Apostle speaks as if saying: they act this way so that it may be said of them that they filled up the measure of their sins always, at every time, in every period of their historical life, before the Lord Jesus, during His time, and after Him, throughout their whole history.
It was permitted them to rise up against us and against the Lord Himself, so that even in this period they would not be without an act of fighting against God (Photius in Oecumenius). They did so much evil to the ancient prophets, and in our time to Christ the Lord and to us, so that their sins might always be filled up. Since they always acted in this way, they were always filling up their sins.
Or the Apostle wants to say: they sinned before, but it was still bearable. But when at last they rose up against God Himself and His holy Gospel, by this the measure of their sins was filled. They can no longer be endured. The Lord said: "And you fill up the measure of your fathers" (Mt 23:32), that is, complete what was lacking in them.
In this case always will mean forever, as when we say: once and for all, that is, finally. Theophylact writes: "They did and do this to the ancient prophets, then to Christ, and finally to us, in order to show that they hasten to reach the full measure of sins, their utmost limit."
But the wrath of God has come upon them to the end. Has come to the end means that the measure of longsuffering has been fulfilled. The final determination of God's judgment upon them has taken place, and their lot has been decided. Thus Chrysostom says: "By saying the wrath has come, the Apostle showed that it must inevitably follow, for it has been appointed and foretold."
Or it may be understood thus: the wrath of God always followed after them, and now it has overtaken them and come close. It is about to thunder forth. Or to the end means final wrath. It will strike completely, there will be no restoration, and no mercy is to be expected.
It is evident that the Apostle has in view the Lord's prophecy about the destruction of Jerusalem and the scattering of the people. They sinned before, and God punished them with a view to correction. Now, however, a final wrathful punishment follows for resistance to God's purposes, which were so manifest and so saving both for them and for all men.
Without these purposes, men cannot attain their own end. They go contrary to the God-appointed course of humanity's restoration. Therefore they are not worthy to be preserved. When the Apostle wrote this, the beginnings of oppression by the Romans had already appeared. They indicated that what the Lord had foretold was near its fulfillment.
Saint Chrysostom says of this: "For them there will no longer be what there was before. There is no time for repentance. There is no place for God's longsuffering. Inevitable wrath is coming. From what is this evident? From Christ's prophecy."
With particular force Oecumenius paraphrases this apostolic accusation of the Jews: "The Apostle brings a great accusation against the Jews. For he says that everything the Jews did, they did with the purpose of sinning. That is, they found pleasure in sins and sinned, so as to fill up their sins, as if in this way: they sinned as though paying a debt with sins.
Let them say that they killed the Lord out of ignorance. But why did they beat the prophets, who were honored? Why did they drive us out? Why do they do evil to you? Why do they hinder the Gentiles from being saved? If the conversion of the Gentiles to Christ is good, why, while not being converted themselves, do they place obstacles before the conversion of others? But if they do not consider this good, why do they envy those who are converted? And what business do they have with the Gentiles?
Do you see how they sin from sheer love of sin and do everything to fill up their sins, that is, so that they may never remain without sins? For this reason, he says, the wrath of God has already come upon them to the end. Wrath always pursued them when they sinned, but it was restrained, giving room for repentance. Now, however, it has overtaken them.
Wrath, he orge with the article, shows that what is meant here is that very wrath which long ago should have fallen upon them. To the end means that it will no longer be as before: slavery and again liberation, captivity and again return, the wrath of God and again mercy. Now the wrath of God is upon them to the end. There will no longer be deliverance from calamities."
